Application iledNovember 28, 1903. Serial No. 182,983. (Remodel.)`

vimproved construction for brooders' for thev artificial vwarming of chicks.

My invention consists in the construction, arrangement, and combination of elements hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawings, in which.-

Figure 1 is a perspective A illustrating the complete brooder. section of the broeder. Fig` 3 isa cross-section of the brooder at right/angles to Fig. 2. In the construction of the broeder, as shown, the numeral 10- designates thefront wall, 11 the. rear wall, and 12 1'3 the end walls, of a casing, preferably of rectangular form in plan view. The casing is subdivided by transverse partitions 14 `15 of the same y,height as and parallel with the end walls 12 L13, the ends of the partitions being fixed to the front and' rear walls. Ventilating ports or ues 16 are formed in and near the upper. margins of the front and rear walls of the casing adjacent the inner faces'of the transverse partitions 14 15. A door 17 -is hinged in an opening in the rear wallll of the casing and provided Withconventional means for holding the same closed. An oxygen-port 18 is formed in the lower portion of the door 17 and covered by a plate 19, spaced apart from the outer face-of 'the door and open at its ends, whereby atmospheric air may enter through the port 18 at the rear of said plate by lateral draft as contradistinguished to a direct draft through said port if.

the plate were omitted. A loor 20y is mounted on the casing-and supported by the walls and partitions thereof, and a plate 21, preferably of sheet metal, is mounted von the lower face of said ioor and secured by nailing through the margins of the plate into the floor.. A lamp' 22 is removably and replaceably placed between the vpartitions 14 15 and front andrear walls of the casing directly beneath the sheetmetal plate 21, and the heat from the chimney Fig. 2 is alcngitudinal` egress of chicks thereto.

be of material and considerable weight, such of said lamp contacts with and -is deflected by said plate. An aperture 23 is formed in the iioor 2O above the yplate 2l and is arranged to receive and contain a jug 24 or other containing vessel in contact with and supported by the sheet-metal plate. Cold-air tubes 25 26 are mounted horizontally in the floor 2O and communicate 'between the end portions of said floor and the aperture 23. It is the function of the cold-air tubes 25 26 to convey atmospheric -air from the exterior of ythe casing to thespace surrounding the jug 24 in the aperture 23.I A second lioor 27 is mounted on the first iloor. andis provided with-` an aperture 28, through which the -jug' 24 may pass. Tubes 29` 30 are mounted vertically in and extend through the floor 27, and it is the function of said tubes to supply air from the space. surrounding the jug to the space above said loor. A

A brooder-house or top casing composed of the front Wall 31, rear wall 32 'of less height than the frontl wall, end walls 33 33, and an inclined top 3,4 is provided and mounted onthe base or lower casing and surrounds the floor 27. One of the end walls 33 of the brooderhouse or upper casing is provided with Aan ingross-port 35, to which a runway 36 or inclined platform may approach, as illustrated in Fig. 1. Al glazed opening is provided in the front wall 31 of the brooder-house or casing, and ventilators 37 38 are provided lin said.

front'wall on either side .of the glazed opening or window. The cold-air' fiues 25 26 extend through theend walls 33 33 of the brooderhouse or casing, preferably by reason `of notches in the lowen margins of said end walls overlapping said tubes. A door 39 is formed in the inclined cover- 34 of the broederhouse or upper casing and' is `hinged at one end for vertical oscillation to4 provideaccess to the brooderroom. A three-sided frame 40 'is mounted in the broeder-house or upper lcasing and supported by posts 41 41, fixed to or resting on the oor 27. The frame 40 is covered with fabric 42, and the margins of said fabricde'pend from each bar of the frame andthe floor 27 and are slitted a distance above said floor for convenient ingress and The fabric 42 should IOO as a good grade of canton-anuel, in order that it may bear a considerable amount of usage and offer considerable resistance to the radiation of heat. The fabric 42 surrounds` the jug 24 and has an aperturein its center, through which the neck of the jug protrudes, and vapor given 0E by the heat of the water in the jug isv discharged outside the warm room inclosed by the fabric or hover. It is to be understood that the space inclosed by the fabric 42 and the depending slitted margins thereof will be maintained at ahigher temperature than the space within the brooderhouse or upper casing surrounding Isaid fabric, thus providing a warm room in 'which chicks may seek 'shelterfrorn a lower temperature on the outside. for the chicks to run in and out of the warm room frequently, taking refuge in the warmer temperature whenever they desire to do so, and on occasion playing about the brooderhouse or upper casing o r even in the atmospheric air outside the casing on the runway or adjacent thereto.

It will be observed that the space between the partitions -14 15 and the front and rear walls of the lower casing constitutes a fur` nace-chamber supplied with oxygen through the Lport 18 and having vents or iiues 16. rl `he spaces at the ends of the casing have the function of limiting and restricting the radiation of heat from the furnace-chamber, but are unoccupied. rlhe port 35, whereby the chicks may pass to and from the brooder-house or upper casing, may be closed by a door., as illustrated in Fig. l.

l claim as my inventionl. The brooder, comprising a casing con- In practice it is usualand communicating between the exterior of the casing and the space around said waterreceptacle, a brooder-house or upper casing surrounding said floor, air ingress and egress ports for the furnace-chamber, air-egress ports for the brooder-house or upper casing, and a door in said upper casing.

2. Abrooder, comprising a casing provided with air ingress and egress ports and a door, a lamp removably andV replaceably mounted in said casing, a floor on said casing, which floor is'apertured, a sheet-metal plate mounted on said oor and crossing the aperture therein, a water-receptacle on said sheet-metal plate within said aperture, a hover surrounding said receptacle and supported by the Hoor,

and a housing inclosing said hover and recep tacle and supported by the floor.

3. A broeder, comprising a casingformed with a furnace-chamber, ventilators and means of access to said chamber, a floor on said casing and formed with an aperture, a sheetfmetal plate on said Hoor crossing the aperture therein, cold-air pipes leading through said Hoor to said aperture, awater-receptacle in said aperture of the floor and supported by said sheet-metal plate, a second floor on the rst oor and provided with an aperture tb receive the water-receptacle, Ventilating-pipes mounted in the floor, a hover surrounding the water-receptacle and resting on the floor, and a housing surrounding and covering the waterreceptacle and hover and provided with means of ingress and egress.
